Definitions
- the present invention relates to a bulb socket and to an assembling or mounting method therefor.
- a bulb socket disclosed in Japanese Unexamined Patent Publication No. 2003-31328 has been conventionally known.
- This bulb socket is such that terminal fittings are provided in a fitting portion in the form of a rectangular tube, into which a base portion of a wedge-base bulb is insertable, resilient holding pieces formed at the terminal fittings are engaged with retaining projections of the base portion with the base portion inserted in the fitting portion, and the base portion is retained and held by this engaging action.
- the leading end of the base portion might get into a clearance between a surrounding wall forming the fitting portion and the resilient holding piece to inadvertently deform the resilient holding piece inward away from the surrounding wall of the fitting portion.
- a method for mounting a frame-shaped cover at the opening portion of the fitting portion as disclosed in Japanese Unexamined Patent Publication No. H10-284204 may be thought as a countermeasure. Since the resilient holding pieces can be covered by the cover mounted at the opening portion of the fitting portion, it can be avoided that the base portion comes into contact with the resilient holding piece to inadvertently deform it.
- the base portion Upon mounting the wedge base bulb into the bulb socket, the base portion is inserted into the fitting portion while the wedge base bulb is moved with a light emitter thereof held by a chuck of an assembling apparatus. Since wedge base bulbs are generally made of glass and have large dimensional tolerances, an amount of displacement between a base portion and a light emitter is large in some of them. Thus, even if the chuck and the light emitter are moved to specified positions, there is a likelihood that the position of the base portion is displaced with respect to the fitting portion. In such a case, the base portion might interfere with the cover to hinder its insertion into the fitting portion.
- the present invention was developed in view of the above situation and an object thereof is to enable a base portion of a wedge base bulb to be reliably mounted in a bulb socket including a cover for protecting a resilient holding piece at least partly accommodated in a fitting portion.
- a bulb socket comprising:
- the cover can be displaced in conformity with the position of the base portion even if the base portion is displaced with respect to the fitting portion, the base portion can be reliably mounted into the fitting portion.
- the resilient holding piece is arranged to extend along the inner circumferential surface of the fitting portion.
- the cover is substantially frame-shaped and/or wherein the cover is mounted at or to an opening edge portion of the fitting portion.
- At least one projection is formed on the outer surface of the one or more wall portions, preferably of each of the pair of wall portions.
- the cover is so displaceable as to be inclined with respect to the fitting portion by coming into line or point contact with the fitting portion, preferably with the projection thereof.
- a projection is formed on the outer surface of each of the pair of wall portions, and the cover is so displaceable as to be inclined with respect to the fitting portion by coming into line or point contact with the projection.
- the cover can be displaced to be inclined in conformity with the position of the base portion even if the base portion is displaced with respect to the fitting portion, the base portion can be reliably mounted into the fitting portion.
- At least one guiding slant is formed at the opening edge of a through hole of the cover for permitting the insertion of the base portion.
- the base portion can be reliably guided into the through hole.
- the cover one or more resilient locking pieces for locking the cover to the fitting portion, wherein the resilient locking pieces preferably extend substantially along an arrangement direction of the cover to the fitting portion to interact with one or more locking protrusions of the fitting portion.
- the resilient locking piece is substantially U-shaped as a whole by being comprised of a pair of lateral sections and a locking section connecting the lateral vertical sections, wherein the resilient locking piece is resiliently deformable in a direction intersecting the arranging direction with parts connected with a main portion of the cover substantially as supporting points.
- a method of mounting or a wedge base bulb into a bulb socket comprising the following steps:
- At least one projection is formed on the outer surface of the one or more wall portions, preferably of each of the pair of wall portions and/or wherein the cover is so displaceable as to be inclined with respect to the fitting portion by coming into line or point contact with the fitting portion, preferably with the projection thereof.
- a bulb socket 10 of this embodiment is made e.g. of a synthetic resin, a first or upper portion (preferably a substantially upper half area) thereof serves as a fitting portion 11 substantially in the form of a (preferably substantially rectangular or polygonal) tube having an open distal or upper side, and a second or lower portion (preferably a substantially lower half area) thereof serves as a receptacle 12 into which an unillustrated connector is or can be at least partly fitted or inserted.

- Such restricting walls 14 are resiliently deformable substantially outward of the fitting portion 11 together with resilient holding pieces 23 to be described later. Since the restricting walls 14 themselves have a certain rigidity, they function to suppress forward and backward movements of a cover 30 to be described.
- One or more, preferably a pair of locking protrusions 15 are so formed on the outer surface of (preferably each of) the front and/or rear walls 13F, 13R as to locate the restricting wall 14 adjacent thereto, preferably substantially therebetween, and one or more projections 16 are formed below the respective locking protrusions 15.

- the (preferably each of the) other terminal fittings 20 includes one tab 21 projecting downward into the receptacle 12, at least one resilient contact piece 22 to be at least partly accommodated in the fitting portion 11 and at least one resilient holding piece 23 to be likewise at least partly accommodated in the fitting portion 11.
- Each resilient holding piece 23 projects or stands upward in the fitting portion 11 and preferably extends substantially along the inner surface of the front wall 13F and/or rear wall 13R of the fitting portion 11.
- a base portion 51 of a wedge base bulb 50 is inserted or mounted into the fitting portion 11 in a mounting direction MD, the resilient holding pieces 23 are engaged with retaining projections 54 of the base portion 51, whereby an upward detachment (or detachment in a direction substantially opposite to the mounting direction MD) of the base portion 51 from the fitting portion 11 is prevented and the resilient contact pieces 22 are resiliently held in contact with terminal portions 53 on the outer surface of the base portion 51 to be electrically connectable or connected.
- the cover 30 made e.g. of a synthetic resin is mounted on or to the bulb socket 10.
- the cover 30 includes a main portion 31 substantially in the form of a (preferably substantially rectangular or polygonal) frame and formed with a (preferably substantially laterally long rectangular) through hole 32 vertically penetrating the main portion 31, and one or more, preferably two pairs of front and/or rear resilient locking pieces 33 extending substantially downward from the (preferably substantially opposite) lateral (left and/or right) end(s) of (preferably the front and/or rear edge portions of) the main portion 31.
- One or more rib-shaped projections 34 are formed to transversely extend along the front and/or rear edge portions of the upper surface of the main portion 31.
- the respective rib-shaped projections 34 are arranged in transversely intermediate parts (preferably substantially in transversely middle parts), and the distal or upper surfaces thereof are one or more guiding slants 35 sloped down (or in amounting direction MD) toward the inner sides (toward the through hole 32).
- the upper opening edge of the through hole 32 preferably has the opposite left and/or right edges thereof obliquely cut to form one or more tapered surfaces 36.
- One or more escaping recesses 37 for avoiding interference with the respective resilient holding pieces 23 with the cover 30 assembled with the bulb socket 10 are formed on the lower surfaces of the front and/or rear edge portions.
- one or more guiding plates 38 extending substantially downward are formed on the lateral (left and/or right) edge portions of the main portion 31.
- Each resilient locking piece 33 preferably is substantially U-shaped as a whole by being comprised of a pair of lateral (left and right) substantially vertical sections 39 and a locking section 40 connecting (preferably the bottom ends of) the lateral (left and right) vertical sections 39.
- This locking section 40 has at least its transverse intermediate (preferably substantially middle) part thereof obliquely cut from the inner surface to the lower surface to form at least one guiding groove 41.
- the inner surfaces of the resilient locking pieces 33 (surfaces substantially facing the outer surfaces of the front and/or rear walls 13F, 13R with the cover 30 mounted on the fitting portion 11) serve as substantially facing surfaces 42.
- Such resilient locking pieces 33 are resiliently deformable forward and backward with the upper ends (parts connected with the main portion 41) substantially as supporting points.
- the cover 30 is so assembled with the bulb socket 10 as to at least partly cover the fitting portion 11 from above (or from the mounting direction MD).
- the guiding plates 38 of the cover 30 are at least partly fitted or inserted into the guiding recesses 17 of the fitting portion 11, whereby the cover 30 is positioned substantially in forward and backward directions and/or transverse directions (directions at an angle different from 0° or 180°, preferably substantially orthogonal to an assembling direction AD of the cover 30) with respect to the fitting portion 11.
- the one or more locking sections 40 of the resilient locking pieces 33 come into contact with the respective one or more locking protrusions 15 and the resilient locking pieces 33 are resiliently deformed to be more distanced from the front and/or rear walls 13F, 13R while the one or more guiding grooves 41 are engaged with the one or more locking protrusions 15. If the locking sections 40 pass the locking protrusions 15, the resilient locking pieces 33 are resiliently at least partly restored and the locking sections 40 become engageable with the locking protrusions 15 from below (or a direction substantially opposite to the assembling direction AD), thereby completing the assembling of the cover 30.
- the main portion 31 With the cover 30 assembled, the main portion 31 is placed on or engages the distal or upper surface of the opening edge of the fitting portion 11, the front and/or rear edge portions of the main portion 31 are located along the inner periphery of the opening of the fitting portion 11 to at least partly cover parts of the resilient holding pieces 23 (particularly parts close to the front wall 13F and the rear wall 13R) in the fitting portion 11 (see FIGS. 1 to 4 ).
- the intrusion of external matters into a clearance between the upper ends of the resilient holding pieces 23 and the inner circumferential surface of the fitting portion 11 can be prevented by these front and/or rear edge portions. Since the upper ends of the resilient holding pieces 23 at least partly enter the escaping recesses 37, there is no likelihood that the cover 30 interferes with the resilient holding pieces 23.
- the lower surfaces of the locking protrusions 15 and the upper surfaces of the locking sections 40 are vertically spaced apart (or spaced apart along the assembling direction AD) to form one or more clearances Ca for permitting the cover 30 to be inclined forward and backward with respect to the bulb socket 10 (see FIGS.
- the one or more projections 16 preferably are arranged substantially at the same height as the one or more locking sections 40, and the projections 16 and the inner surfaces (facing surfaces 42) of the locking sections 40 are in such a positional relationship as to be held or holdable in contact or face each other in horizontal direction (forward and backward directions or a direction at an angle different from 0° or 180°, preferably substantially normal to the assembling direction AD) while defining a tiny clearance therebetween.
- the cover 30 can be inclined forward and backward (directions intersecting with or at an angle different from 0° or 180°, preferably substantially normal to an inserting or mounting direction MD of the wedge base bulb 50 into the fitting portion 11) with either the front or rear projections 16 substantially as supporting points so as to displace the resilient locking piece 33 corresponding to the projections 16 at the opposite side upward (see FIGS. 3 and 4 ).
- a maximum upward displacement of the resilient locking pieces 33 at this time preferably is equivalent (or corresponds) to the clearance Ca between the locking protrusions 15 and the locking sections 40.
- a distance between the outer surfaces of the pair of guiding plates 38 is shorter than a distance between the inner surfaces of the pair of guiding recesses 17 and a distance between the pair of left and right vertical sections 39 of the resilient locking piece 33 is set longer than the with of the locking protrusions 15 (see FIG. 6 ).
- the cover 30 is relatively displaceable in transverse direction (or in a direction at an angle different from 0° or 180°, preferably substantially normal to the mounting direction MD) with respect to the fitting portion 11 due to these dimensional differences.
- the wedge base bulb 50 to be mounted into the bulb socket 10 includes the base portion 51 e.g. made of glass and preferably in the form of a substantially rectangular plate and a light emitter 52 e.g. made of glass and continuous with the upper end edge of the base portion 51.
- Two pairs of terminal portions 53 extending from a filament (not shown) at least partly accommodated in the light emitter 52 extend downward in or toward the base portion 51, are drawn out from the base portion 51 through (preferably the bottom end surface of) the base portion 51, and are folded (preferably substantially upward) to extend along the front and/or rear outer surfaces of the base portion 51, wherein one pair preferably is arranged at the front side and the other pair preferably is arranged at the rear side.
- the retaining projections 54 are respectively formed on the opposite front and rear surfaces of the base portion 51.
- the base portion 51 is at least partly inserted into the fitting portion 11 from above (in the mounting direction MD) to be at least partly accommodated therein.
- the resilient contact pieces 22 are so resiliently brought into contact with the respective terminal portions 53 as to be electrically connectable and the folded portions of the resilient holding pieces 23 are engaged with the retaining projections 54, whereby the detachment of the base portion 51 from the fitting portion 11 can be prevented.
- a chuck (not shown) of an automatic apparatus holds the light emitter 52 to at least partly insert the base portion 51 into the fitting portion 11 through the through hole 32 of the cover 30 in the mounting direction MD or from above.
- the bottom end edge of the base portion 51 comes into contact with the front and/or rear guiding slants 35, whereby the cover 30 is inclined forward or backward and the position of the through hole 32 is displaced forward or backward to follow the base portion 51 as the cover 30 is inclined.
- the base portion 51 can enter the through hole 32 and, consequently, can be inserted into the fitting portion 11.
- the resilient locking piece 33 being displaced upward when the cover 30 is inclined forward or backward is inclined to approach the front or rear wall 13F or 13R, whereas the resilient locking piece 33 at the opposite side is inclined away from the rear or front wall 13R or 13F without hardly vertically moving (see FIG. 4 ).
- the (preferably substantially frame-shaped) cover 30 for at least partly covering the resilient holding pieces 23 and permitting the insertion of the base portion 51 is mounted at (preferably the opening edge portion of) the fitting portion 11, and the one or more clearances Cb for permitting the cover 30 to be displaced in forward and/or backward directions intersecting with the mounting direction MD of the base portion 51 into the fitting portion 11 are formed adjacent to or between the outer surfaces of the pair of substantially parallel wall portions (front and/or rear walls 13F, 13R) of the fitting portion 11 and the facing surfaces 42 of the cover 30 substantially facing the pair of wall portions.
- the one or more projections 16 preferably are respectively formed on the outer surfaces of the front and rear walls 13F, 13R and the cover 30 is brought or bringable preferably into line contact with the projections 16, whereby the cover 30 is displaced while being inclined.
- the cover 30 can be inclined in conformity with the position of the base portion 51, wherefore the base portion 51 can be reliably mounted into the fitting portion 11.

Description
- The present invention relates to a bulb socket and to an assembling or mounting method therefor.
- A bulb socket disclosed in Japanese Unexamined Patent Publication No.
2003-31328 - Since the resilient holding pieces are exposed at an opening portion of the fitting in the above bulb socket, the leading end of the base portion might get into a clearance between a surrounding wall forming the fitting portion and the resilient holding piece to inadvertently deform the resilient holding piece inward away from the surrounding wall of the fitting portion.
- A method for mounting a frame-shaped cover at the opening portion of the fitting portion as disclosed in Japanese Unexamined Patent Publication No.
H10-284204 - The following problem still remains even with the structure for covering the resilient holding pieces by the cover. Upon mounting the wedge base bulb into the bulb socket, the base portion is inserted into the fitting portion while the wedge base bulb is moved with a light emitter thereof held by a chuck of an assembling apparatus. Since wedge base bulbs are generally made of glass and have large dimensional tolerances, an amount of displacement between a base portion and a light emitter is large in some of them. Thus, even if the chuck and the light emitter are moved to specified positions, there is a likelihood that the position of the base portion is displaced with respect to the fitting portion. In such a case, the base portion might interfere with the cover to hinder its insertion into the fitting portion.

One or more escapingrecesses 37 for avoiding interference with the respective resilient holdingpieces 23 with thecover 30 assembled with thebulb socket 10 are formed on the lower surfaces of the front and/or rear edge portions. Further, one ormore guiding plates 38 extending substantially downward are formed on the lateral (left and/or right) edge portions of themain portion 31. - Each
resilient locking piece 33 preferably is substantially U-shaped as a whole by being comprised of a pair of lateral (left and right) substantiallyvertical sections 39 and alocking section 40 connecting (preferably the bottom ends of) the lateral (left and right)vertical sections 39. Thislocking section 40 has at least its transverse intermediate (preferably substantially middle) part thereof obliquely cut from the inner surface to the lower surface to form at least one guidinggroove 41. The inner surfaces of the resilient locking pieces 33 (surfaces substantially facing the outer surfaces of the front and/orrear walls cover 30 mounted on the fitting portion 11) serve as substantially facing surfaces 42. Suchresilient locking pieces 33 are resiliently deformable forward and backward with the upper ends (parts connected with the main portion 41) substantially as supporting points. - The
cover 30 is so assembled with thebulb socket 10 as to at least partly cover thefitting portion 11 from above (or from the mounting direction MD). In the processing of assembling thecover 30, the guidingplates 38 of thecover 30 are at least partly fitted or inserted into the guiding recesses 17 of thefitting portion 11, whereby thecover 30 is positioned substantially in forward and backward directions and/or transverse directions (directions at an angle different from 0° or 180°, preferably substantially orthogonal to an assembling direction AD of the cover 30) with respect to thefitting portion 11. Thereafter, as thecover 30 is further assembled, the one ormore locking sections 40 of theresilient locking pieces 33 come into contact with the respective one ormore locking protrusions 15 and theresilient locking pieces 33 are resiliently deformed to be more distanced from the front and/orrear walls grooves 41 are engaged with the one ormore locking protrusions 15. If the lockingsections 40 pass the lockingprotrusions 15, theresilient locking pieces 33 are resiliently at least partly restored and the lockingsections 40 become engageable with the lockingprotrusions 15 from below (or a direction substantially opposite to the assembling direction AD), thereby completing the assembling of thecover 30. - With the
cover 30 assembled, themain portion 31 is placed on or engages the distal or upper surface of the opening edge of thefitting portion 11, the front and/or rear edge portions of themain portion 31 are located along the inner periphery of the opening of thefitting portion 11 to at least partly cover parts of the resilient holding pieces 23 (particularly parts close to thefront wall 13F and therear wall 13R) in the fitting portion 11 (seeFIGS. 1 to 4 ). The intrusion of external matters into a clearance between the upper ends of theresilient holding pieces 23 and the inner circumferential surface of thefitting portion 11 can be prevented by these front and/or rear edge portions. Since the upper ends of theresilient holding pieces 23 at least partly enter the escapingrecesses 37, there is no likelihood that thecover 30 interferes with theresilient holding pieces 23. - With the
main portion 31 of thecover 30 substantially placed on the distal or upper surface of thefitting portion 11, the lower surfaces of the lockingprotrusions 15 and the upper surfaces of the lockingsections 40 are vertically spaced apart (or spaced apart along the assembling direction AD) to form one or more clearances Ca for permitting thecover 30 to be inclined forward and backward with respect to the bulb socket 10 (seeFIGS. 3 and6 ), and the outer surfaces of the front andrear walls resilient locking pieces 33 are spaced apart in forward and backward directions (or spaced apart in a direction at an angle different from 0° or 180°, preferably substantially normal to the assembling direction AD) to form clearances Cb for permitting thecover 30 to be inclined forward and backward with respect to the bulb socket 10 (seeFIG. 3 ). The one ormore projections 16 preferably are arranged substantially at the same height as the one ormore locking sections 40, and theprojections 16 and the inner surfaces (facing surfaces 42) of the lockingsections 40 are in such a positional relationship as to be held or holdable in contact or face each other in horizontal direction (forward and backward directions or a direction at an angle different from 0° or 180°, preferably substantially normal to the assembling direction AD) while defining a tiny clearance therebetween. By the above clearances Ca and Cb, thecover 30 can be inclined forward and backward (directions intersecting with or at an angle different from 0° or 180°, preferably substantially normal to an inserting or mounting direction MD of thewedge base bulb 50 into the fitting portion 11) with either the front orrear projections 16 substantially as supporting points so as to displace theresilient locking piece 33 corresponding to theprojections 16 at the opposite side upward (seeFIGS. 3 and4 ). A maximum upward displacement of theresilient locking pieces 33 at this time preferably is equivalent (or corresponds) to the clearance Ca between the lockingprotrusions 15 and the lockingsections 40. - In transverse direction, a distance between the outer surfaces of the pair of guiding
plates 38 is shorter than a distance between the inner surfaces of the pair of guidingrecesses 17 and a distance between the pair of left and rightvertical sections 39 of theresilient locking piece 33 is set longer than the with of the locking protrusions 15 (seeFIG. 6 ). Thus, thecover 30 is relatively displaceable in transverse direction (or in a direction at an angle different from 0° or 180°, preferably substantially normal to the mounting direction MD) with respect to thefitting portion 11 due to these dimensional differences. - The
wedge base bulb 50 to be mounted into thebulb socket 10 includes thebase portion 51 e.g. made of glass and preferably in the form of a substantially rectangular plate and alight emitter 52 e.g. made of glass and continuous with the upper end edge of thebase portion 51. Two pairs ofterminal portions 53 extending from a filament (not shown) at least partly accommodated in thelight emitter 52 extend downward in or toward thebase portion 51, are drawn out from thebase portion 51 through (preferably the bottom end surface of) thebase portion 51, and are folded (preferably substantially upward) to extend along the front and/or rear outer surfaces of thebase portion 51, wherein one pair preferably is arranged at the front side and the other pair preferably is arranged at the rear side. Preferably, the retaining projections 54 (preferably having a substantially rectangular triangular or pointed cross section) are respectively formed on the opposite front and rear surfaces of thebase portion 51. Thebase portion 51 is at least partly inserted into thefitting portion 11 from above (in the mounting direction MD) to be at least partly accommodated therein. In this state, theresilient contact pieces 22 are so resiliently brought into contact with the respectiveterminal portions 53 as to be electrically connectable and the folded portions of theresilient holding pieces 23 are engaged with the retainingprojections 54, whereby the detachment of thebase portion 51 from thefitting portion 11 can be prevented. - Next, functions of this embodiment are described.
- Upon mounting the
wedge base bulb 50 into thebulb socket 10, a chuck (not shown) of an automatic apparatus holds thelight emitter 52 to at least partly insert thebase portion 51 into thefitting portion 11 through the throughhole 32 of thecover 30 in the mounting direction MD or from above. At this time, if the position of thebase portion 51 is displaced in a direction intersecting the mounting direction MD (e.g. forward or backward), the bottom end edge of thebase portion 51 comes into contact with the front and/or rear guiding slants 35, whereby thecover 30 is inclined forward or backward and the position of the throughhole 32 is displaced forward or backward to follow thebase portion 51 as thecover 30 is inclined. In this way, thebase portion 51 can enter the throughhole 32 and, consequently, can be inserted into thefitting portion 11. - The
resilient locking piece 33 being displaced upward when thecover 30 is inclined forward or backward is inclined to approach the front orrear wall resilient locking piece 33 at the opposite side is inclined away from the rear orfront wall FIG. 4 ). - When the
cover 30 is inclined forward or backward, the rib-shapedprojection 34 come into contact with the restrictingwall 14, thereby preventing an excessive inclination of thecover 30. This prevents theresilient locking pieces 33 from being excessively deformed beyond their resiliency limits. - In the
bulb socket 10 of this embodiment, the (preferably substantially frame-shaped) cover 30 for at least partly covering theresilient holding pieces 23 and permitting the insertion of thebase portion 51 is mounted at (preferably the opening edge portion of) thefitting portion 11, and the one or more clearances Cb for permitting thecover 30 to be displaced in forward and/or backward directions intersecting with the mounting direction MD of thebase portion 51 into thefitting portion 11 are formed adjacent to or between the outer surfaces of the pair of substantially parallel wall portions (front and/orrear walls fitting portion 11 and the facing surfaces 42 of thecover 30 substantially facing the pair of wall portions. Thus, even if thebase portion 51 is displaced forward or backward with respect to thefitting portion 11, the position of thebase portion 51 can be accordingly displaced forward or backward, wherefore thebase portion 51 can be reliably mounted into thefitting portion 11. - Further, the one or
more projections 16 preferably are respectively formed on the outer surfaces of the front andrear walls cover 30 is brought or bringable preferably into line contact with theprojections 16, whereby thecover 30 is displaced while being inclined. Thus, even if thebase portion 51 is displaced with respect to thefitting portion 11, thecover 30 can be inclined in conformity with the position of thebase portion 51, wherefore thebase portion 51 can be reliably mounted into thefitting portion 11. - Since the one or more guiding slants 35 preferably are formed at the opening edge of the through
hole 32 of thecover 30 for permitting the insertion of thebase portion 51, thebase portion 51 can be reliably guided into the throughhole 32. - Accordingly, to reliably mount a base portion of a wedge base bulb in a bulb socket including a cover for protecting resilient holding pieces in a fitting portion, a frame-shaped
cover 30 for at least partly covering one or more resilient holdingpieces 23 is mounted at or to or close to an opening edge portion of afitting portion 11, and one or more clearances Cb for permitting displacements of thecover 30 in forward and/or backward directions intersecting with a mounting direction MD of abase portion 51 with respect to thefitting portion 11 is/are defined between the outer surface(s) of (preferably a pair of) wall portion(s) (front and/orrear walls fitting portion 11 and thecover 30. Even if thebase portion 51 is displaced forward or backward with respect to thefitting portion 11, thecover 30 can be displaced in conformity with the position of thebase portion 51, wherefore thebase portion 51 can be reliably mounted into thefitting portion 11. - The present invention is not limited to the above described and illustrated embodiment. For example, the following embodiments are also embraced by the technical scope of the present invention as defined by the claims.
- (1) Although the guiding slants are formed at the opening edge of the through hole in the foregoing embodiment, they may not be formed or formed in a different number according to the present invention.
- (2) Although the cover is displaced to be inclined with respect to the fitting portion in the foregoing embodiment, it may be parallelly moved with respect to the fitting portion according to the present invention.
- (3) Although the wedge base bulb of the double bulb type in which two terminal portions are arranged on each of the front and rear surfaces of the base portion is described in the foregoing embodiment, the present invention is also applicable to wedge base bulbs of the single bulb type in which one terminal portion is arranged on each of the front and rear surfaces of the base portion.
- (4) Although the projections formed on the front and rear walls are brought into line contact with the cover in the foregoing embodiment, they may be brought into point contact according to the present invention.
